Abstract

A method and apparatus for detonating a power charge in downhole wellbore using a heating element embedded within the energetic material of the power charge.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A tool for use downhole comprising:
 a firing head; 
 a setting tool; 
 a power charge cartridge assembly disposed within the setting tool, further comprising: 
 tubular housing with a first end, second end, and a longitudinal axis, an energetic material disposed within the hollow tubular housing, an igniter disposed in the tubular housing adjacent to the energetic material, wherein the igniter comprises a heating element and an initiation charge. 
 
     
     
       2. The apparatus of  claim 1  wherein the heating element is in direct contact with the energetic material. 
     
     
       3. The apparatus of  claim 1  wherein the igniter is located proximate to the first end of the tubular housing. 
     
     
       4. The apparatus of  claim 1  wherein the igniter is located proximate to the second end of the tubular housing. 
     
     
       5. The apparatus of  claim 1  wherein the setting tool comprises a power charge chamber with a first end and a second end, and a ported sub, wherein the ported sub is coupled to the second end of the power charge chamber and slideably engaged to the second end of the tubular housing. 
     
     
       6. The apparatus of  claim 1  wherein the heating element is a resistor. 
     
     
       7. The apparatus of  claim 1  further comprising an addressable switch integral with the power charge cartridge assembly, where the addressable switch controls the application of electrical energy to the heating element. 
     
     
       8. The apparatus of  claim 3  further comprising a first electrical conductor outside the first end of the tubular housing and electrically coupled to the heating element. 
     
     
       9. The apparatus of  claim 8  further comprising a second electrical conductor connecting the heating element to the tubular housing. 
     
     
       10. The apparatus of  claim 3  further comprising an electrical conductor outside the power charge cartridge assembly and electrically coupled to the heating element. 
     
     
       11. The apparatus of  claim 3  further comprising a first electrical conductor connecting the heating element to the tubular housing. 
     
     
       12. The apparatus of  claim 4  further comprising a first electrical conductor outside the first end of the tubular housing and electrically coupled to the heating element. 
     
     
       13. The apparatus of  claim 11  further comprising a second electrical conductor connecting the heating element to the tubular housing. 
     
     
       14. The apparatus of  claim 12  further comprising a second electrical conductor outside the power charge cartridge assembly and electrically coupled to the heating element. 
     
     
       15. The apparatus of  claim 4  further comprising a first electrical conductor connecting the heating element to the tubular housing. 
     
     
       16. A power charge cartridge assembly comprising:
 a tubular housing with a first end and a second end; 
 an energetic material disposed within the tubular housing; and 
 an igniter disposed in the tubular housing adjacent to the energetic material, wherein the igniter comprises a heating element and an initiation charge. 
 
     
     
       17. The apparatus of  claim 16  wherein the heating element is a resistor. 
     
     
       18. The apparatus of  claim 16  wherein the igniter is proximate to the first end of the tubular housing. 
     
     
       19. The apparatus of  claim 16  wherein the igniter is proximate to the second end of the tubular housing. 
     
     
       20. The apparatus of  claim 16  further comprising an addressable switch integral with the power charge cartridge assembly, wherein the addressable switch controls the application of electrical energy to the heating element. 
     
     
       21. The apparatus of  claim 18  further comprising a first electrical conductor outside the first end of the tubular housing and electrically coupled to the heating element. 
     
     
       22. The apparatus of  claim 21  further comprising a second electrical conductor connecting the heating element to the tubular housing. 
     
     
       23. The apparatus of  claim 21  further comprising a second electrical conductor outside the power charge cartridge assembly and electrically coupled to the heating element. 
     
     
       24. The apparatus of  claim 18  further comprising a first electrical conductor connecting the heating element to the tubular housing. 
     
     
       25. The apparatus of  claim 19  further comprising a first electrical conductor outside the first end of the tubular housing and electrically coupled to the heating element. 
     
     
       26. The apparatus of  claim 24  further comprising a second electrical conductor connecting the heating element to the tubular housing. 
     
     
       27. The apparatus of  claim 25  further comprising a second electrical conductor outside the power charge cartridge assembly and electrically coupled to the heating element. 
     
     
       28. The apparatus of  claim 19  further comprising a first electrical conductor connecting the heating element to the tubular housing.
